Fastek Soft-Controller for DO-178B Software Verification and Validation

LTS-1000 Lighting Tester and High Speed Data Logging System

Programmable RF Attenuator

RFA-1000 Digital Attenuators

Fastek introduces a line of high-power, digitally-controlled RF attenuators. Multiple attenuators can be cost effectively controlled by one PXI driver.

One of the many benefites is that complete calibration of RF paths can be measured for integration within the test station and LabVIEW control.

PXI maximizes the integration and synchonization of various Test/Measurement components including Signal Generators, Analyzers, and RF Switches.

Instrument Driver Sofware and Soft Front Panel are included (multi-processor & multi-OS support). Optional FPGA Control provides Dynamic Attenuation Profiling.
